Subject: Re: Rake: How do I Override Var's Used by a Rule?


This is really starting to feel like I am having a conversation with 
myself...

Even if this is the correct way to do this, it would be really nice to 
know how to override var's from the command line. For example, with 
make, I could do the following:

make -f mymakefile OPT1="new_val" OPT2="over_new_val" mytarget

This would override value for OPT1 and OPT2 in the makefile. Is there 
something equivalent in rake?



Thanks,
B
